I’m with you for the same reason: demographics.
The entire basis of Israel’s existence is as a Jewish homeland, the last safe place on Earth for Jews. To my mind that comes first. Thus a two-state solution is the only way forward.
But then there’s also this:
Gulf Arab states cover an enormous amount of territory. Some of them could readily carve out a New Palestine and easily fund all of the construction needed to raise its cities and towns up from the desert.
Rather than fight over a tiny piece of land in an already tiny country, why not build something new and set an example?
It’s not as if the world isn’t already facing mass migrations due to other aspects of the planetary population/resource/ecology crises. A mass migration to a New Palestine could also set the example for handling the other anticipated mass migrations of the next two centuries.
Do i understand your proposal correctly? 1: one or more Gulf Arab states should 'carve out' some land in the desert. 2: they should build "cities and towns." 3: the millions of people from the land their families have lived for generations will move there? Is that about right?
